setcolumns() not support canonical name?

[binocular222]

This not work: setcolumns("Extra 4", 48)
That means I have to find out which name of "Extra 4" is, but how?

FYI: tagitems() support ex1-ex5
P.S: This not work too: <prop ex4>

OK, next beta it will work with "Extra 4".

I think that we should have a naming convention:
<prop ex4>
tagitems("ex4")
setcolumns("ex4", 48)
